In truth, it is a global variable accessed with the funny name of Egg::e. You can choose whether global things are allowed to use it by whether you make it public.
static functions in a class work the same way... In truth they are global functions accessed via classname::function().

je::scope
JE::Scope(3pm) User Contributed Perl Documentation JE::Scope(3pm)
NAME
JE::Scope - JavaScript scope chain (what makes closures work)
DESCRIPTION
JavaScript code runs within an execution context which has a scope chain associated with it. This class implements this scope chain. When a
variable is accessed the objects in the scope chain are searched till the variable is found.
A JE::Scope object can also be used as global (JE) object. Any methods it does not understand will be delegated to the object at the bottom
of the stack (the far end of the chain), so that "$scope->null" means the same thing as "$scope->[0]->null".
Objects of this class consist of a reference to an array, the elements of which are the objects in the chain (the first element being the
global object). (Think of it as a stack.)
METHODS
find_var($name, $value)
find_var($name)
This method searches through the scope chain, starting at the end of the array, until it finds the variable named by the first
argument. If the second argument is present, it sets the variable. It then returns an lvalue (a JE::LValue object) that references the
variable.
new_var($name, $value)
new_var($name)
This method creates (and optionally sets the value of) a new variable in the variable object (the same thing that JavaScript's "var"
keyword does) and returns an lvalue.
The variable object is the first object in the scope chain (searching from the top of the stack) that is a call object, or
"$scope->[0]" if no call object is found.
CONSTRUCTOR
None. Just bless an array reference. You should not need to do this because it is done for you by the "JE" and "JE::Object::Function"
classes.
